Abstract (en)

[origin: EP3029089A1] A fiber-reinforced composite material obtained by reinforcing a matrix resin with fibers, wherein the matrix resin contains a thermoplastic resin and a carbon black, the fibers are discontinuous carbon fibers, a part of the discontinuous carbon fibers forms fiber bundles, and the thickness of a thinnest part of the matrix resin which is located between an outermost surface of the composite material and the fibers existing in an inside of the composite material is less than 100 µm. Further, it is preferred that the thermoplastic resin is a polyamide-based resin, that the discontinuous carbon fibers have a length of from 3 to 100 mm, and that the orientation of the discontinuous carbon fibers is random. Furthermore, it is preferred that the size of the primary particle diameter of the carbon black is within a range of 7 to 75 nm.
